BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 788,009, dated April 25, 1905.

Application filed April 1,1904. Serial No. 201.156.

To ll'lmm/ it llblr l/ calmer/.0:

Be it known that I, JOHN I\I. \VILSON, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Baling-Presses, of which the following is a specification.

My invention relates to impr vements in baling-presses provided with means for antomatically condensing and feeding each charge of hay into the baling-chamber; and it consists in mechanism for accelerating twothirds of the pitmans forward stroke with the least expenditure of power, a trip-lever for operating said mechanism and completing the forward stroke of the pitman, mechanism for increasing the leverage of the feeder as it condenses each charge, and mechanism connecting the feeder to the trip-lever, so the pitman and the feederwill operate in sequence.

)Iinor features of the invention will here inafter appear, and in order that said invention may be fully understood reference will now be made to the accompanying drawings, in which* Figure I is a broken plan view of a balingpress embodying my improvements with the sweep removed and pitman about to start on its forward stroke. Fig. 2 is a horizontalsection of the power end of the baling-press taken above the trip-lever, showing the position of the pitman after completing about two-thirds of its forward stroke. Fig. 3 is an enlarged horizontal section of the power end of the baling-press, taken on line III III of Fig. 4. Fig. I is a vertical section of the power end of the press, taken on line IV IV of Fig. 1. Fig. 5 is a broken horizontal section of the power end of the press, taken on the same plane as Fig. 2, showing the pitman at the end of its forward stroke. Fig. 6 is a vertical section of the baling-chamber and hopper, taken on line VT VI of Fig. 1, showing the operation of the feeder by dotted lines. Fig. 7 is a front elevation of the hopper and feeder. Fig. 8 is a broken detail side elevation of the hopper, showing part of the mechanism for operating the feeder. Fig. 9 is a broken detail perspective view of an auxiliary pitman forming part of the invention.

In said drawings, 1 designates a bed-plate having a circular forward end 2 and rigidly secured at its rear end to the bottom wall of a bailing-chamber 3, provided with an opening a in its upper wall for the admission of the usual division-block and provided at its sides with retainers 5. The press is carried on wheels 6, mounted upon axles 7, arranged be neath the circular end of the bed-plate and the l)aling-chamber.

S designates a stationary shaft projecting upwardly through the center of circular portion 2 for the reception of a circular trip-lever 9, provided with an upwardly-extending hub 10, ournaled on the shaft and formed integral at its upper end with a cross-head II provided at its opposite ends with the customary sweep I2 and its brace 13.

14 designates three equally-spaced depending lugs formed integral with the under side of the trip-lever, each of said lugs having an upwardly-extending stub-shaft I5 and a similar downwardly-cxtending shaft 16, upon which are journaled rollers 17 1S, respectively, the latter being arranged slightly in advance of the former, as shown in Fig. 5. The trip-lever is supported upon a pedestal 19, formed integral with the center of circular portion 2, and said trip-lever is removably held in position by a nut- 20, engaging the upper threaded end of shaft 8.

21 designates a pitman secured at its forward end to a head-block 22 and provided near its central upper portion with a shoulder 23.

22 designates a rearwardly-extending apron secured at its forward end to one side of the head-block for the purpose of closing feed-opening 3, communicating with one side of the baling-chamber, as the head-block makes its forward stroke.

24 designates a lever of the third class fulcrumed at one end upon a stub-shaft 25, projecting upwardly from a post 26, formed integral with one side of the bed-plate adjacent to the trip-lever. The opposite end of lever 24 is pivotally secured to the rear end of an auxiliary pitman 27, the forward end of which is adapted to contact with shoulder 23 and advance the pitman about two-thirds IOC its forward stroke by one of rollers 17 con tacting with the reverse curve 29, forming part of the rear edge of lever 24, whereby the free end of the latter is swung forward to the position shown in Fig. 2, where it is retained until the roller clears the pivoted end of the lever by curved portion 30, forming part of the rear edge of the latter, said curve being concentric with the center of shaft 8 when the lever occupies the position shown in said figure. When roller 17 has nearly cleared the pivoted end of lever 24, the latter is immediately drawn to the position shown in Fig. 5 by a retractile spring 31, connected at its opposite ends to the pivoted end of the lever and the adjacent side of the bed-plate. Lever 24 is supported in a horizontal position by a U-shaped bracket 32, secured to the upper side of the bed-plate.

33 designates a lever of the first class fulcrumed upon a stub-shaft 34, projecting upwardly from a post 35, formed integral with the, upper side of an arm 36, extending for wardly from the circular portion of the bedplate. Said lever is pivotally connected at its free end to a connecting-bar 37, pivotally secured at its forward end to a rod 38, slidingly arranged in guides 39, secured to the under side of the bed-plate and the balingchamber. Rod 38 is returned to the end of its backward stroke by one of rollers 17 contacting with the curved edge 40 of lever 33, along which it travels until it contacts with a communicating curve 41, concentric with the center of shaft 8, when the lever has reached the end of its backward stroke, as shown in Fig. 5. The lever is held in this position until the roller contacts with its straight edge 42, along which it travels until it clears the free end 43 of said lever. During the travel of the roller along the straight portion 42 of lever 33 the free end of the latter is moved to the end of its forward stroke, as indicated by dotted lines, Fig. 1, and thus advances rod 38 to the end of its forward stroke. As the fulcrum-point of lever 33 is arranged to one side of the trip-lever, the latter will not become locked from further movement when one of its rollers, 17, engages the hook formed at the juncture of curve 41 with straight edge 42.

44 designates a hopper communicating at its lower end with feed-opening 3 and consisting of sheet-metal sides 45 and a quad rant-shaped bottom 46, extending from the lower portion of feed-opening 3 in the baling-chamber to feed-opening 47 in the upper front portion of the hopper.

48 designates the feeder, consisting of a pair of arms 49, having longitudinal slots 50 and united by a transverse sheet-metal portion 51, which contacts with and forces the charge of hay into the baling-chamber. Arms 49 are pivotally mounted upon a transverse shaft 52, secured to the rear portion of sheetmetal sides 45.

53 designates an apron hinged at 53 to the upper portion of the baling-chamber and resting at its opposite end upon the inner edge of sheet-metal portion 51 in order to direct the charge of hay downwardly toward feed-opening 3.

54 designates a pair of oppositely-disposed slots in sheet-metal sides 45, consisting of segmental portions 54, formed concentric with shaft 52 and communicating with oblique portions 54 communicating at their lower ends with vertical portions 54 55 designates a transverse shaft extending through slots 50 and 54 and provided at its opposite ends 'with rollers 56 and links 57.

58 designates a pair of cables attached at their opposite ends to links 57 and staples 59 59, secured to the side of rod 38 between guides 39. Cables 58 operate over sheavewheels 60 61 at the upper and lower portions of sheet-metal sides 45.

62 designates a pair of cables attached at their opposite ends to links 57 and staples 59 59 Said cables operate around sheavewheels 63, ournaled beside sheave-wheel 61.

64 designates tracks secured to the outer surface of sides 45 adjacent to and paralleling the oblique and vertical portions of slots 54 for rollers 56 to travel on, and thus relieve these portions of slots 54 from wear by the contacting shaft 55.

Assuming that the different parts occupy the positions shown in Fig. 1, the operation will be as follows: The rotation of trip-lever 9 will bring one of rollers 17 into contact with the reverse curve 29 and traveling along said edge will swing the free terminal of the lever to the end of its forward stroke, carrying therewith the auxiliary pitman 27, which advances pitman 21 about two-thirds of its stroke, bringing its rear concave end in the path of one of rollers 18, which moves the pitman, to the end of its forward stroke. After completing its forward stroke the pitman contacts with bracket 32, which prevents it from following roller 18, so that when the latter passes out of contact therewith the pitman will be retracted by the eX- pansion of the hay in the baling-chamber and retractile spring 21 secured at its opposite ends to the pitman and the bed-plate. Roller 17 clears the fulcrumed end of lever 24 and permits spring 31 to retract the auxil- ITO iary pitman before the rebound of pitman 2]. occurs in order to prevent shoulder 23 from striking the end of said auxiliary pitman.- A charge of hay is forced into the baling-chamber in advance of the plunger by the feeder, which is drawn down to the dotted position shown in Fig. 6 by one of the rollers 17 traveling along the straight edge 42 of lever 33, causing the free end of the latter to swing forward with rods 37 38. The forward movement of rod 38 pulls cables 62 downwardly, together with shaft 55, which latter lowers the feeder. As shaft moves through the concentric portions of slots 54 it will be retained by the latter close to the fulcrumed point of the feeder, and thus accelerate the speed of the same until it begins to condense the charge of hay in the narrow throat 46 of the hopper preparatory to forcing the charge through the small feed-opening 3. As the feeder begins to condense the charge it is lent increasing power until lowered to a vertical position, by shaft 55 advancing to the forward ends of slots 50, which movement is ac complished by the oblique and vertical portions of slots 54, which increase the distance between the downwardly-moving shaft 55 and the fulcrum of the feeder. \Vhile it is condensing and forcing the charge of hay through feed-opening 3 the strain produced by the tendency of said charge to expand is transferred from the front ed 'es of the ob lique and vertical portions of sIots 54 to rollers 56 and tracks 64, and after the feeder has been lowered to a vertical position the strain occasioned by the tendency of the charge to expand before the advancing plunger is transferred from cables 62 to rollers 56 and the vertical lower ends of tracks 64. By making said opening 3 less in height than the balingchamber, as shown in Fig. 6, a charge of hay when forced into the latter has an opportunity to expand a certain degree, and thus relieve the feeder of undue strain and insure the proper operation of the latter by preventing a portion of the hay from getting caught between the end of the feeder and the lower end of the feed-opening. The feeder is held in a lowered position until the plunger has advanced slightly beyond the feed-opening by roller 17 traveling along the straight edge 42, which is of such length that the roller clears its outer terminal just as the plunger passes the feedopening. The feeder is then raised almost immediately to receive another charge by the following roller 17 engaging the curved edge -ll) of lever 33, swinging the free end of the latter backward with rods 37 38, which latter draws downwardly on cables 58, and thus raises the feeder to the position shown in full lines, Fig. 6, before the plunger completes its backward stroke.

From the above description it is apparent that by giving the charge of hay its initial compression with the feeder in the throat of the hopper before it is forced into the balingchamber the plunger will not be compelled to compress said charge to the usual extent, and as the feeder condenses the charge before the plunger begins to compress the same it is evi dent that the work will be more evenly distributed on the team. Furthermore, the work of holding the feeder in a depressed position will be transferred from the team to rollers 46 and the vertical portions of tracks 64.
